The pressure half-time index is the time it takes for the initial maximal pressure gradient in diastole to fall by 50%. In patients with mild aortic regurgitation, this fall in pressure is gradual.

There’s room on the market for new TAVI valves as long as they can compete with the best in practice, a researcher says.

regurgitation was combined with valvular stenosis, with a maximum gradient greater than 45 mm Hg. Despite this, BAV currently does not represent an obstacle to obtaining eligibility to practise ...

Patients who underwent transcatheter aortic valve replacement (TAVR) with a valve designed to treat aortic regurgitation had an overall mortality rate of just 8.1% at one year, well below the trial's ...

JenaValve today announced new results from an expanded cohort receiving its Trilogy transcatheter heart valve (THV) system.

device developed specifically for the treatment for aortic regurgitation has met all the prespecified safety and efficacy goals, so far, in an expansion cohort of the ALIGN-AR trial, paving the ...

with a valve designed to treat aortic regurgitation had an overall mortality rate of just 8.1% at one year, well below the trial's prespecified goal of 25% to show non-inferiority, according to a ...
